My neighbors have been losing chickens to a killer that takes the head and leaves the rest. Last night we forgot to close up our girls. I will regret this for a long time. The killer went into the coop, took our Brahma's head and left her dear body. There were feathers everywhere in the coop. I don't know of any animal that would do this. Any real predator would take meat for babies or self, but not this killer. My DH thinks it's a bobcat (we have those), but why leave the body untouched and take the head only? I'm one sad chicken mom. Every one of our chickens has a name; this one was Mary.
